Your service is absolutely hands down the most cost effective marketing tool I have ever seen - and your service just gets better and better!
I'm pretty stunned at how well your service works -- it's easily one of the most intuitive applications I've ever used. Most important, it seems to work! It took me only about an hour to get a newsletter through the test point. My highest compliments.
I just wanted to let you know how much I have enjoyed and continue to appreciate your company. It has been a blessing for saving hours upon hours of personally dealing with e-mails and has turned out to be more affordable than I thought.
